MACHINE FOR BENDING SHOVEL-HANDLE3.

SPECIFICATION forming part of Letters Patent No. 368,475, dated August 16, 1887.

Application filed December 13, 1886. Serial No. 221,348. (No model.)

To all whom it may concern.-

Be it known that I, \VILLIAM HOLMAN JOHN- in the county of Franklln, of the State of Maine, have invented a new and useful Improvement in Machinery for Bending Shovel-Handles or Various other Articles of Wood and I do hereby declare the same to be dcscribedin the following specification, and represented in the accompanying drawings, of which- Figure 1 is a top view, Fig. 2 an end elevation, Fig. 3 a front elevation, and Fig. 4 a rear view, of a machine embodying my invention, the nature of which is defined in the claims hereinafter presented. The above-mentioned figures show the positions of the several parts of the machine preparatory to the introduction into it ofa shovel-handle for being bent by it. Fig. 5 is a top view of the machine, representing a shovel-handle, H, in and bent by it. Fig. 6 is a horizontal section taken through the hinges of the several jawsections.

The machine consists of two or more seetional vises, A and (l, constructed, connected, arranged, and having mechanism for operating them substantially as hereinafter described.

In the drawings, A is a vise fixed on aplatform, B, the stationary jaw of such vise being shown at a and its rnovablejaw at I), eachjaw,to enable it to adapt itself to an article to be grasped between them, beingslitted downward a short distance from its top, as shown at c. Themovable jaw is hinged at its lower part to the fixed jaw a, a screw, cZ, going through the movablejaw and screwing into the fixed jaw, and being for the purpose of moving the movable jaw toward the stationaryjaw. The movable jaw constitutes one of a series of jaw-sections, 12, c,f, and 9, connected by hinges h, so as to enable each section 6, f, or g to be turned or moved laterally relatively to the section b.

The sectional vise O is composed of a single jaw, h, and a set ofjaw-sections, i, it, Z, and m, such jaw-sections being arranged edge to edge, and connected by hinges a, so as to enable them to swing laterally. The jaw it, at its lower end or foot, is hinged to the jaw-section i, and is provided with a clamping-screw, it,

which goes through such jaw h and screws into the section t.

The jaw-section m is arranged in the rear of jaw-section 9, both sections being hinged together at or near their feet, and they are provided with a clampingscrew, Z, which. goes through the section g and screws into the section at. A strut, it, extends in one direction from the jaw a, while another such strut, 0,

projects in the opposite direction from the fellow jaw, I). Like struts, p and q, extend from the jaws e and f, and there is attached to the three struts o, p, and q a belt, r, to limit the distances of movement of the struts p and q relatively to the strut 0. Furthermore, from the jaws 1', 7c, Z, and an other struts, r, s, t, and a, project, they being connected bya band, 0, to limit their movements apart from each other.

From the strut r a stud, w, is extended down through a slot, or, in an arm, 7 pivoted to the strut a, and arranged as represented. The said stud and slot are to allow the vise 0 while moving from its position shown in Fig. 1. to that represented in Figs. 5 and 6 to move toward the vise A and maintain its parallelism relatively thereto. The struts q and a are joined to the arms of alever, .2, by connectingrods (1. and b, pivoted to such lever and to the said struts, the said lever being arranged as represented and fulerumed to a post, 0. Furthermore, there is in rear of the jaw a, and journaled in projections d e therefor, an upright shaft, f, having two arms, 9, extending from it. Each of the said arms, by a link, 7L2, is connected with the jaw-section m, each link being pivoted to its arm and to such jaw-see tion. The said shaftf, arms y, and links 71 are to prevent the movable vise O and the jawsections between it and the vise A from swaying or tipping laterally out of their vertical positions while in movement.

On taking hold of the longer arm ofthe levemand moving it inward the jaw-sections and their movable struts may be moved into positions as shown in Fig. 5, so as to bend the shovel-handle Hin the requisite manner when it is grasped between the jaws of the sectional vises.

Before being introduced into the machine such shovel-handle or piece of wood to be bent is to be steamed, to render it more or less soft and yielding. After having been inserted and clamped within the jaws of the Vises the sectional jaws are to be moved laterally, as may be required, to bend the handle or piece of wood in the desired manner.

I claim- 1. A wood-bending machine, substantially as described, consisting of vises A and 0, each of which has one of its jaws in sections and arranged and connected by hinges, as set forth, the terminal sections 9 and m of two next adj acent vises being arranged one in front of the other and provided with a clamping-screw, and hinged together at or near their feet, as explained, and such Vises being provided with mechanism for moving their jaw-sections latand one terminal section of one sectional jaw is arranged in rear of that of the other sectional jaw, and with it provided with a clamp- 30 ing-screw, all being substantially and for use as set forth."
